If a fraction has 10 as its denominator, then we can write its decimal expansion by putting the decimal point after one number from the left.
Example:
[tex]\frac{325}{10} =32.5[/tex]
If a fraction has 100 as its denominator, then we can write its decimal expansion by putting the decimal point after two numbers from the left.
Example:
[tex]\frac{1325}{100} = 13.25[/tex]
